Description

Technical Field

[0001] The present invention relates to the technical field of automotive safety supplies, and more particularly, to a seat greeting method and a child seat. Background Art

[0002] A child seat is mainly used to be installed on an automotive seat for infants and young children to ride. In order to enable users to conveniently place infants and young children on the child seat and fix them after opening the car door, existing child seats are equipped with an automatic rotation function. As long as the car door on one side of the child seat is opened, the child seat will automatically rotate and present a greeting state towards the car door. However, sometimes users do not carry infants and young children, and only need to open the car door at the corresponding position to pick up items. After the car door is opened, the child seat will still automatically rotate to the greeting state, resulting in low accuracy of greeting and sending children by the child seat and bringing trouble to users. Summary of the Invention

[0003] To solve at least one of the above problems, the present invention first provides a seat greeting method, including the steps of: judging whether the car door is opened according to the car door information;

[0006] If there is a passenger on the seat body, obtaining the riding duration and judging whether the riding duration exceeds a preset duration;

[0007] If the riding duration exceeds the preset duration, judging whether the seat body rotates to the greeting mode according to the crowd information outside the car.

[0008] Optionally, the crowd information includes the state of only adults, the state of only children, and the state of adults carrying children; the step of, if there is no passenger on the seat body, judging whether the seat body rotates to the greeting mode according to the crowd information outside the car and the crowd getting-on demand information includes:

[0009] If there is no passenger on the seat body and the crowd information is the state of only adults, the seat body remains in the original state;

[0010] If there is no passenger on the seat body and the crowd information is the state of only children or the state of adults carrying children, obtaining the crowd getting-on demand information and judging whether the seat body rotates to the greeting mode.

[0011] Optionally, the crowd information includes only the adult status and the adult-with-child status; when the riding duration exceeds a preset duration, the step of determining whether the seat body rotates into the welcome mode according to the crowd information outside the vehicle door includes:

[0012] Determine whether the adult is a guardian according to the crowd information;

[0013] If the crowd information is only the adult status and the adult is not a guardian, the seat body remains in the original state;

[0014] If the crowd information is only the adult status and the adult is a guardian, the seat body rotates into the welcome mode.

[0015] Optionally, when the crowd information is only the adult status and the adult is not a guardian, the step of the seat body remaining in the original state further includes: sending a reminder signal to the guardian.

[0016] Optionally, the crowd information includes only the child status and the adult-with-child status; when the riding duration exceeds a preset duration, the step of determining whether the seat body rotates into the welcome mode according to the crowd information outside the vehicle door includes:

[0017] If the crowd information is only the child status or the adult-with-child status and the adult is not a guardian, the seat body remains in the original state;

[0018] If the crowd information is the adult-with-child status and the adult is a guardian, the seat body will rotate to the welcome mode.

[0019] Optionally, it further includes the step of: when the seat body is in the welcome mode, after obtaining a reset instruction, controlling the seat body to rotate to the correct riding position.

[0020] Optionally, the step of, when the seat body is in the welcome mode, after obtaining a reset instruction, controlling the seat body to rotate to the correct riding position includes:

[0021] When the seat body is in the welcome mode, determine whether there is a passenger on the seat body according to the riding information on the seat body. If there is a passenger on the seat body, obtain the passenger information and generate reset position information according to the passenger information;

[0022] When receiving a reset instruction, obtain the reset position information and control the seat body to rotate to the correct riding position.

[0023] Optionally, the reset position information includes seat orientation information, seat pitch angle information, headrest height information and / or wing deployment degree information, and the reset instruction includes a gesture instruction, which is independently created by the user; when the reset instruction is received, the step of obtaining the reset position information and controlling the seat body to rotate to the correct sitting position includes:

[0024] When the reset instruction received is the first gesture, the seat orientation, seat pitch angle, headrest height and / or wing deployment degree of the seat body are controlled according to the reset position information.

[0025] Optionally, the passenger information includes date of birth, weight range, and height range.

[0026] Compared with the prior art, the beneficial technical effects of the present invention are:

[0027] 1. After the car door is opened, the seat information is first judged to see if there is a child on the seat body, and then the external scene of the seat body is judged to see if there is a child and whether the child needs to sit. Only after it is determined that there is a need to sit will the seat body rotate to the welcoming mode, which improves the welcoming accuracy of the seat body and solves the problem of the seat body welcoming guests after opening the car door.

[0028] 2. When the passenger information indicates that there are passengers, the seat body will rotate to the welcoming mode after the door is opened and only the guardian is present, so that the guardian can take the child off the seat body. If the adult is not the guardian, the guardian will be reminded, which not only improves the accuracy of the seat body in welcoming and sending off, but also improves safety, and is not conducive to people other than the guardian taking the child off the seat body;

[0029] 3. After placing the child on the seat, the seat can be reset by gesture commands. The seat will rotate to the corresponding position, such as forward or backward, according to the acquired passenger information. In addition, different electric functions of the seat can be adjusted by different gesture commands, and handheld commands can be created by yourself. The whole operation is more intelligent, which improves the interactive experience.

[0030] 4. When the riding information shows that there are passengers, the riding time and crowd information will be combined to determine whether the passengers need to get off and whether they meet the requirements for getting off, and then control whether the seat body is turned to the welcoming mode. Multiple information will be coordinated to make accurate judgments for different situations, further improving the welcoming accuracy of the seat body and greatly increasing the intelligence of the seat body;

[0031] 5. After entering the passenger information on the seat body or mobile application, the passenger will be recognized every time they take a ride subsequently, and will be automatically reset to the correct orientation and angle suitable for that age group according to their date of birth when resetting, without the need to enter the passenger information every time they travel, which improves the convenience during travel under the effect of intelligence.

[0032] In addition, the present invention provides a child seat for implementing the seat greeting method as described above.

[0033] Compared with the prior art, the advantages of the child seat of the present invention and the above seat greeting method compared with the prior art are the same, and will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 is a flowchart of a seat greeting method according to an embodiment of the present invention;

[0035] Figure 2 is a flowchart of another seat greeting method according to an embodiment of the present invention;

[0036] Figure 3 is a flowchart of yet another seat greeting method according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following further elaborates on the present application Figures 1-3 with reference to the accompanying drawings.

[0038] In a first aspect, an embodiment of the present invention provides a seat greeting method. Among them, the seat body is installed on an automobile seat for a child to ride and can greet and send off the child. The seat body includes a base fixed on the automobile seat and a seat body rotatably provided on the base. A motor is provided on the base, and a gear is provided on the seat body. The motor drives the gear to drive the seat body to rotate relative to the base, thereby realizing greeting and sending off the child and resetting to the correct position.

[0039] Referring to Figures 1-3 , the seat greeting method includes the following steps:

[0040] Judge whether the door is opened according to the door information.

[0041] Among them, the initial position of the seat body does not face the side of the car door close to the seat body. The door information is that the door on the side close to the seat body is closed or opened. The welcome condition is that the car is in a stationary state and the door on the side close to the seat body is opened. A speed sensor module can be set on the seat body or the car. Whether the car is in a stationary state can be identified through the speed sensor module. In this embodiment, it is preferably that the speed sensor module is arranged on the seat body. At least one visual recognition camera is arranged on the seat body. The visual camera can recognize the trajectory of the door opening, and then judge whether the door on the corresponding side of the seat body is in an open state. In another implementation manner, a distance sensor is arranged on the seat body. The distance sensor is used to measure the distance between the seat body and the corresponding door, so as to judge whether the door is opened. When the door on the corresponding side of the seat body is opened, the welcome condition is triggered. If the door is in a closed state, then the seat body is in the original state.

[0042] If the door is opened, the occupancy information on the seat body will be monitored and obtained.

[0043] The occupancy information includes the state of having a passenger and the state of having no passenger. The state of having a passenger here means that there is a child sitting on the seat body; the state of having no passenger means that there is no child sitting on the seat body. Among them, the occupancy information can be identified and determined through the visual recognition camera on the seat body. In another implementation manner, a pressure sensor will be arranged on the seat body, and the occupancy information will be obtained by sensing the pressure through the pressure sensor. At the same time, the door information is obtained and confirmed again through the visual recognition camera. The door information includes the door being opened and the door being closed. If the door is closed, the seat body remains in the original state.

[0044] If there is no passenger on the seat body, it is judged whether the seat body rotates to the welcome mode according to the crowd information outside the car and the crowd boarding demand information.

[0045] Among them, after the door opening is recognized, the crowd information at the car door is collected again through the visual recognition camera according to the obtained occupancy information. The crowd information includes the state of only adults outside the car, the state of only children outside the car, and the state of adults carrying children outside the car. It should be noted in this step that the visual recognition camera for obtaining the crowd information can be the same as the visual recognition camera for obtaining the occupancy information; it can also be different visual recognition cameras. In this embodiment, it is preferably that the visual recognition camera for obtaining the crowd information and the visual recognition camera for obtaining the occupancy information are two separate visual recognition cameras, so that the recognition and acquisition of different information can be completed more efficiently.

[0046] When the crowd information indicates that there are adults with children, the crowd boarding demand information is the boarding demand indication signal for adults. For example, after the door is opened, the guardian holds the child and has an action of approaching the interior of the vehicle, or an eye movement tracking module is provided on the seat body. When the adult's gaze stays on the seat body for more than the set duration. If the above crowd boarding demand information is met, then the seat body rotates to the welcome mode. If not, the seat body does not rotate to the welcome mode.

[0047] When the crowd information indicates that there are only children, the crowd boarding demand information is the boarding demand indication signal for children. For example, after the door is opened, the child has an action of approaching the interior of the vehicle, or an eye movement tracking module is provided on the seat body. When the child's gaze stays on the seat body for more than the set duration. If the above crowd boarding demand information is met, then the seat body rotates to the welcome mode. If not, the seat body does not rotate to the welcome mode.

[0048] Among them, the user can customize the face of the child's guardian through the visual recognition camera in the crowd information, and after obtaining the adult information, it will be judged whether the adult is the guardian.

[0049] Among them, the seat body rotating to the welcome mode means that: the seat body rotates and faces the corresponding side door for the convenience of the child getting on or off the vehicle.

[0050] When the occupancy information is the no-passenger state and the crowd information obtained only indicates the adult state, the seat body remains in the original state, and the original state means that the seat faces the front or rear of the vehicle.

[0051] When the occupancy information is the no-passenger state and the crowd information obtained only indicates the child state, the visual recognition camera will judge whether the child has a boarding demand. Only when the child has a boarding demand will the seat body rotate to the welcome mode for the convenience of the child to take a seat. The boarding demand can be that after the door is opened, the child has an action of approaching the interior of the vehicle. Or an eye movement tracking module is provided on the seat body. When the child's gaze stays on the seat body for more than the set duration, then it will be determined that the child has a boarding demand, and the seat body rotates to the welcome mode.

[0052] When the riding information shows that there are no passengers, and the crowd information obtained shows that the adult is carrying a child, a visual recognition camera is required to identify whether the adult is a guardian. If the adult is not a guardian, the seat body will not rotate to the welcome mode. If the adult is a guardian, the visual recognition camera will determine whether the child needs to get on the bus. Only when the child needs to get on the bus will the seat body rotate to the welcome mode to facilitate the child to get on. The need to get on the bus can be the child moving closer to the car after the door is opened, or the guardian holding the child moving closer to the car. Or the seat body is equipped with an eye tracking module. When the guardian's eyes stay on the seat body for more than a set period of time, it will be determined that there is a need to get on the bus, and the seat body will rotate to the welcome mode.

[0053] If there is a passenger on the seat, the passenger's riding time will be obtained to determine whether the riding time exceeds the preset time.

[0054] The seat body will be provided with a safety belt buckle. When the child sits on the seat body and the safety belt is connected to the safety belt buckle, the time program will be started. In another embodiment, a pressure switch can also be provided on the seat body. After the child sits on the seat body, the pressure switch is turned on and the time program is started. Specifically, the user can set a preset time (such as 5 minutes, 10 minutes, etc.) on the terminal device. After the time program is started, if the child has just sat on the seat body and has not exceeded the preset time, the seat body will remain in its original state; during this period, it will be judged whether the child needs to get off the car, such as if the child cries; or according to the humidity detector set on the seat, it is judged that the child leaves the seat body because the diaper needs to be changed, then it is judged that the child has the need to get off the car. At this time, after the car door is opened, an adult needs to issue a command to the seat body to control the seat body to rotate to the welcoming mode.

[0055] If the riding time exceeds a preset time, it is determined whether the seat body is rotated to a welcoming mode based on the crowd information outside the door.

[0056] If the riding time exceeds the preset time, the seat body will be controlled to rotate to the welcoming mode according to the crowd information after the door is opened.

[0057] When the riding information is that there are passengers, and the crowd information obtained is that there are only adults and the adults are not guardians, the seat body is in the original state, and a reminder signal will be sent to the guardian, and the visual recognition camera will take a photo of the corresponding adult and transmit it to the terminal device. The reminder signal can be a reminder sound emitted by the seat body or a text message reminder sent by the terminal to the customer. If the guardian is not near the car, the guardian can view the real-time situation through the visual recognition camera. In addition, the seat belt buckle will lock the seat belt, making it difficult to unfasten the seat belt to prevent children from being taken away by strangers.

[0058] When the occupancy information indicates that there is a passenger and the crowd information obtained shows that there is only a child, the seat body is in its original state.

[0059] When the occupancy information indicates that there is a passenger and the crowd information obtained shows that there is only an adult and the adult is a guardian; or when the crowd information indicates that there is an adult with a child and the adult is a guardian, the seat body rotates to the welcome mode.

[0060] During the welcome mode, the occupancy information is monitored and confirmed again. After issuing a reset command to the seat body, the seat body returns to the correct position.

[0061] Among them, when the seat body rotates to the welcome mode, the corresponding visual recognition camera will monitor and identify the situation on the seat body again. For example, when the seat body rotates to the welcome mode when there is a passenger, if it is recognized that there is no child on the seat body, it is determined that the child has left the seat and got off the vehicle. After the child gets off the vehicle, the guardian can issue a reset command to the corresponding visual recognition camera, and then the seat body will rotate and face the front of the vehicle and return to the preset position in the case of no passenger (the parameters of the preset position can be set by the user through the terminal device).

[0062] When the seat body rotates to the welcome mode when there is no passenger, the user places the child on the seat body and fastens the child with a seat belt. The visual recognition camera will recognize the occupancy status, and then recognize and obtain the passenger information. The passenger information includes the date of birth, weight range, and height range. The date of birth is mainly filled in by the user on the mobile application connected to the seat body. The mobile application can be the corresponding APP or the corresponding mini-program. In other embodiments, the date of birth can be directly input on the seat body.

[0063] Before the child takes a seat, the visual recognition camera will capture the face of the child, then retrieve the date of birth of the child from the database, then calculate the age of the child based on the current date, and then generate the corresponding reset position information. The reset position information includes seat orientation information, seat pitch angle information, headrest height information, and / or wing expansion information. After the seat body receives the reset command, it will rotate to the corresponding reset position. In this way, for children of different ages, the seat body can be rotated to the correct seating position. For example, when a child under one year old takes a seat, the seat body needs to face the rear of the car; when a child between one and seven years old takes a seat, the seat body needs to face the front of the car.

[0064] Among them, the corresponding visual recognition camera can obtain the height information of the child, and the pressure sensor set on the seat body can obtain the weight of the child. After obtaining the height information and weight information of the child, the seat body will adjust the headrest height, wing expansion degree, tilt angle, etc. to the corresponding positions through the corresponding electric device. The whole process does not require much human participation, with high intelligence and high accuracy.

[0065] The reset instruction can be a gesture instruction or a voice instruction. In this embodiment, the reset instruction is preferably a gesture instruction. When the gesture instruction is the first gesture (such as making an OK gesture to the corresponding visual recognition camera), the control system will simultaneously control the seat orientation, seat pitch angle, headrest height and wing expansion degree of the seat body according to the obtained reset position information. When the gesture instruction is the second gesture (such as extending two fingers or giving a thumbs up), the controller can independently control the adjustment of the headrest height. When the gesture instruction is the third gesture (such as extending three fingers), the controller can independently control the adjustment of the wing expansion degree, so that different electric adjustment functions can be adjusted through different gesture instructions of the user. After the seat body is reset according to the reset position information, if the guardian believes that the position still needs to be adjusted, it can be adjusted through the second gesture, the third gesture, etc.

[0066] The gesture instruction can be the number of fingers extended or a gesture made by multiple fingers in cooperation. The corresponding visual recognition camera will recognize the gesture instruction, and the corresponding gesture instruction can be created by the user to design a unique gesture instruction for themselves, thereby improving the interaction experience.

[0067] The user can also set the usage mode (forward, reverse, tilt angle, etc.) of the seat body on the corresponding APP or corresponding mini-program. After the child takes a seat, after the guardian issues a gesture instruction to the corresponding visual recognition camera, the seat body will automatically rotate to the set position. The user can also input the riding information of the corresponding passenger into the corresponding APP or corresponding mini-program. When the child is recognized in the welcome mode, the corresponding electric device will adjust the headrest height and wing expansion degree to the corresponding positions; after the child sits on the seat body and receives the gesture instruction, the seat body will rotate to the corresponding correct position.

[0068] In the embodiment of the present application, during the child's seating stage: after recognizing that the car door is opened, it will first obtain the information of the seat body, make a judgment and determine that there is no child sitting on the seat body, and then make a judgment on the obtained crowd information to determine whether there is a child and whether there is a guardian beside the child. Then it will judge whether there is a need to get on the car. After integrating and judging the obtained multiple pieces of information, the seat body will rotate to the welcome mode to facilitate the child's riding only when it is judged that there is a need to get on the car.

[0069] After the child is seated, an additional verification step is added to ensure that the child is properly seated. After that, the guardian can control the rotation of the seat body to the correct position with just a gesture. During this process, the child's information is obtained, and based on the age, weight, and height, the seat body is driven to rotate to the corresponding orientation, tilt angle, etc., without the user having to make separate adjustments. The entire operation is relatively intelligent.

[0070] Child getting off the seat stage: First, check the situation on the seat body to ensure that there is a child sitting, and at the same time the vehicle is in a stationary state, and only when the door is opened and a guardian is recognized beside the door, the seat body will then rotate to the welcome mode facing the door for the child to get off. Adding the step of verifying the guardian improves safety.

[0071] In addition, for different situations, multiple pieces of information are cross - interconnected and sorted out to more intelligently judge whether to activate the welcome mode, greatly improving the accuracy of welcoming and sending children.

[0072] In a second aspect, another embodiment of the present invention provides a child seat for implementing the seat welcome method in the first aspect above.

[0073] The child seat in this embodiment can greatly improve the accuracy of welcoming and sending children through steps such as detection, recognition, judgment, and verification; prevent children from being taken away by strangers, improving safety; solve the trouble brought to consumers by the current child seats with welcome functions that welcome as soon as the car door is opened; improve the interaction experience with users, making the operation more intelligent and convenient, and making the child seat more intelligent.
